Daniel Suarez has seen a progressive improvement in his Joe Gibbs Racing team, particularly Michigan and Bristol.

The fast-food breakfast wars are heated, apparently.

Subway has ended its four-race sponsorship of Daniel Suarez a race early following an NBC segment with Suarez that included him handing out donuts to fans at New Hampshire.

As news of the Subway move broke over the weekend, there was initial confusion as to why the company had found a clause in its contract to get out. Monday, Joe Gibbs Racing confirmed to ESPN that the segment was the reason Subway used to terminate its sponsorship.

Subway signed with Gibbs as a sponsor for Carl Edwards. It stayed with the team after the health-conscious driver’s abrupt retirement following the 2016 season and Suarez assumed the role as NASCAR spokesperson. It’s hard not to wonder if Subway was not thrilled with the loss of Edwards as its NASCAR pitchman. If the company was happy with the way things were going, why would it be so petty to use something like this to break a contract?

Suarez, the 2016 Xfinity Series champion, is currently 17th in the points standings.
